Hemvac Vacuum Pump Guide – Instructions and Recommendations

Hemvac vacuum pumps are robust, efficient machines designed for industrial, laboratory, and commercial applications. Below, we explain how to use them correctly to ensure maximum performance and durability.

1. Initial Installation

Installation site:

• Well-ventilated area, free from dust, excess humidity, or corrosive vapors
• Stable and level surface to avoid vibrations

Connections:

• Ensure all pipes and hoses are tightly sealed to prevent leaks
• Use inlet filters when working with particles or contaminated vapors

Power supply:

• Make sure the voltage matches the equipment’s specifications
• Use a voltage protector if there are electrical fluctuations

2. Startup

Lubricated (oil-filled) pumps:

• Check the oil level (using the sight glass or dipstick)
• Fill with Hemvac-recommended oil (never mix different types)
• Start the pump with partial vacuum (gradually close the inlet valve)

Dry (oil-free) pumps:

• Ensure the vacuum chamber is free of debris
• Start in test mode to verify proper operation

3. Operation and Maintenance

During operation:

• Monitor the vacuum pressure (avoid overloads)
• For liquid ring pumps, check the level and quality of the liquid (water or special solution)

Preventive maintenance:
✔ Oil change every 500–1000 hours for lubricated pumps
✔ Filter cleaning weekly or based on use
✔ Seal and gasket inspection to prevent leaks

4. Safety and Precautions

• Never operate the pump dry (without oil or sealing liquid)
• Avoid suction of corrosive or explosive gases without proper filters
• Always turn off the pump before performing maintenance

5. Common Applications

• Food industry: Vacuum packaging, dehydration
• Laboratories: Gas extraction, filtration
• Medical sector: Sterilization, suction equipment
